[3] Coinciding with their first headlining tour in 2013, American band the Neighbourhood released three limited-edition 7-inch vinyl singles, with the B-sides containing songs from their supporting acts.

[2] The song was written by George Daniel, Matty Healy, Adam Hann and Ross MacDonald, while the band handled the production alongside Michael and Robert Coles.

[9] Upon release, "Milk" was met with generally positive reviews from contemporary music critics and has since gained the status of a fan-favourite among the 1975's fanbase.

[13] Writing for Consequence, Amanda Koellner said the song "tone[s] things down a bit while holding onto the guitar-heavy, more traditional sound that the latter half of [Sex] offers".

[14] Bre Offenberger, writing for The Post, asserted the song "is basically a jam about cocaine" and listed it at number 19 in a ranking of the band's catalogue.

In his coverage of the performance, Connick noted the song was "stripped free of the musical excess and wordy nature that present-day 1975 thrive on", going on to say the audience's reaction "cut to the heart of what makes [t]he 1975 so special".
